HISTORY OF CENSUS IN MALAYSIA

Population and Housing Census

Before Formation of Malaysia - 1911, 1921,1931, 1947, 1957

After Formation of Malaysia - 1970, 1980,

1991, 2000

Next Census - 2010

slide4

Total Population

1980 - 13,745,241

1991 - 18,379,655

2000 - 23,274,690

2007 - 27.1 million

slide5

Strategy

*To conduct a census, the initial preparation that needs

to be done is the subdivision of whole country into

Enumeration blocks (EBs)

*Ensuring complete coverage of all areas in the country

*The finalization of EB maps was done by state

Offices of the Department

slide6

Census Geography

Prior the census data collection- a system called

geostatistical Census Area was formed

The various geostatistical levels can be subdivided I into two main types:

A. Administrative Areas

B. Statistical Areas

slide7

Census Geography (cont’d.)

  • Administrative Areas
  • Gazetted Boundries
  • - State
  • - Administrative district
  • - Mukim/sub district
  • - Local authority area
  • Statistical Areas
  • - Defined by DOS;
  • - Census districts (CD)
  • - Enumeration Block (EB)
slide8

Census Geography (cont’d.)

Urban Areas

Gazetted areas with their adjoining built-up areas which had a combined population of 10,000 or more at the time of the 2000 population Census

Built-up areas

Built-up areas were contiguous to a gazetted area and at least 60 per cent of their population (aged 10 years and over) engaged in non-agricultural activities as well as having modern toilet facilities in their housing units.

slide10

Statistical Areas

Total EBs for 2000 = 52,877

Total Census Districts = 550

slide11

Overall Activities in Preparation of Census Maps

And Enumeration Block Map (cont’d.)

Started 1998

Decentralised – In Census 2000, the mapping activity was decentralised and undertaken by the 13 state offices with standardised guidelines issued by Headquarters.

Mapping as an ongoing activity in intercensal period – This is important since a good frame is required for household surveys which are conducted on a regular basis.

slide12

Overall Activities in Preparation of Census Maps

And Enumeration Block Map (cont’d.)

*Each EB = 1 enumerator

*Combination of 7 Ebs formed a Cencus Circle (CC)

which was under the responsibility of a supervisor

*A District Superintendent was responsible for

each Census District (CD) comprising about 15

CCs

All District Superintendents in one Administrative District (AD) came under the responsibility of the Assistant Commissioner of Census

Overall Activities in Preparation of Census Maps

And Enumeration Block Map

Two Types of map:

a. Census District Maps

b. Enumeration Blocks (EB)

Census District Maps

- used by Assistant Census Commissioners and

District Superintendents

- purpose for planning and controlling of field work

slide15

Overall Activities in Preparation of Census Maps

And Enumeration Block Map

Census District Maps (cont’d.)

-The map is equivalent to one or part of an Administrative District

-One CD consists about 100 Ebs

- These map contained District and mukim boundaries and various landmarks such as roads, rivers and name of localities

slide17

Overall Activities in Preparation of Census Maps

And Enumeration Block Map

Enumeration Blocks (EB)

- used by enumerators to carry out field work and as a guide map

  • contained 80 – 120 Living Quarters or 500 – 600 persons
  • Map are not according to scale but had a standard size 40cm x 40 cm
slide19

Creation of Census Circles

The Census Circle was a contiguous group of 7 EB’s that was placed under one supervisor. The preparation of the CC did not involve the drawing of any maps, but was a listing of EB’s that formed each CC.

slide20

List Of Census Area

For verification of the census geographical areas, relevant lists served as a guideline and control in the operation of Census activities. Five major lists which were prepared included:

  • Preparation of EB summary by AD and CD
  • Number of enumeration Blocks, Census Circles, Enumerators, Supervisors by CD within Administrative District
  • Preparation of locality lists
  • List of Institutional Living quarters
  • List of Orang Asli (aborigines) EBs
slide21

List Of Census Area

  • Preparation of EB summary by AD and CD

This summary provided a list of normal EB’S and EBs Orang Asli (special EB)

  • Number of enumeration Blocks, Census Circles, Enumerators, Supervisors by CD within Administrative District

-Extracted from the Census Frame Master File

-purposed for recruiting the required number of

enumerators and supervisors for Census operations

-also included the number of Census Circles for each AD

slide22

Preparation of Document 1 (Living Quarters Listing Book)

Objective:

Use by the enumerator during census operations

Contain

a. Sketch Map

b. Boundary Description (M3 Form)

slide23
GIS
  • Embody of hard ware and software configurations designed to support the capture, management, analysis and dissemination of spatial data.
  • Applied to census activities and output, such systems facilitate census cartography, data

capture and linking population data

(demographic and sosio-economics data)

slide24
Socio-economics characteristics

- Education

- Labor force

Household and housing

- Number of person per household

- Type of construction materials

- Population with access to basic facilities

- Tenure status

slide25

PLANNING FOR CENSUS 2010

Strategy:

‘Applying GIS component and application for the mapping activity'. (Spatial data for household and establishment)

Component :

a. Software (Arc Gis Arc View 9.X)

b. Hardware (Plotter, PrinterA3, Workstations)

c. Base Map (JUPEM, JPBD, L.A.A,)

GIS Software were also used for :

  • Analysis on small area statistics (market research, consultant, student)

2. Publishing Census Atlas

slide37

Basic Mapping

The provision of maps serves 2 purposes;

  • Census identification maps locates and show boundaries.

2. Statistical or thematic maps that visualize geographical distribution/patterns.

slide38

Thematic Maps

GIS output can be form of thematic maps

based on census data collected. A collection

of this would form a census atlas which can serve

a wide variety of users and provide and effective

visual presentation (Census Atlas)

slide39

Thematic Maps

  • Can be in the form of;
    • Sub-area
    • Population density
    • Strata (Urban and rural population)
slide43

Conclusion

It is evident that national census data is considered an

important component in planning, development, policy

formulation and decision making. GIS represent an essential information technology component in dealing with collection, managing and analyzing of large spatially referenced data
